Boosting my LS V

Im am starting to put a turbo kit together for my LS Vtec. Plans are for 250-280whp on stock LS Vtec. TO4E turbo and most likely ID 1000cc injectors. I already have a cast turbo mani and most of the piping I will need to make a down pipe. Tuning will be done on my Hondata S100. Build will be slow so stay with me.
